Abstract

Soybean is a grain legume has the ability to fix atmospheric nitrogen in the soil in association with Brady rhizobium rhizobia. Soybean crop fixes 61-337 Kg Nha-1. Many of scientist reported that as macronutrient needs are met, it becomes possible that micronutrient requirements of the soybean plant could be limiting optimum production and although boron is termed a micronutrient, its role within the plant is widespread. The role of boron within the plant includes cell wall synthesis, sugar transport, cell division, differentiation, membrane functioning, root elongation, and regulation of plant hormone levels. The application of lime and boron were given in the plots as per their treatments prior to sowing. The significant increase in the soybean yield was mainly due to increasing does of lime and boron as well. However, the interaction of lime and boron were not fund significant. The maximum seed yield was increased by the application of lime @ 5 t/ha. However on the other hand, increase in the yield by the application of boron 1 kg/ha. When compared with absolute control. It showed that application of lime and boron separately give the positive effect on soybean grain yield whereas in combination with lime and boron could not play significant increase in crop yield.
